how to Total Folders and including files from Windows explorer into listview using drag & drop method at vb.net
View 3 RepliesAsp.net has turned out to be alot easier to use than PHP (so far). However, I have been searching for a while and simply cannot figure this out. How do I get the variables that are contained in the url of my page (that originate from a form that had the method "GET") and utilize them? For example, my page would be [URL]. How would I get the value of some variable?
View 5 RepliesI deleting the files of certain age in a directory and also need to write a log file. So my question is how can we pass a variable from one method to another?
Example : Dotnet.Explorer
Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
Will the list in this shared method keep its state throughout the life of the method? Or will a new list be created every time this method is called?

I have written server code in vb.Net. I want it to read to variables sent by another server's HTTP 'GET' request. For example the first server will send this URL [URL]msgid=$messageid where the values to be used by my server are sender, receiver, msgdata, recvtime and msgid I have written my code but it only reads the address sent by the http server and locates for the file in the server's root directory. I want the server to be reading the variables sent by the other server using the HTTP 'GET' request. My code is shown below
' the web server only accepts get requests.
If Mid(LCase(sbuffer), 1, 3) <> "get" Then

View 6 RepliesI'm trying to make a simple chat client. But it seems that the "Dim ClientData As String = Encoding.ASCII.GetString(RevievedBytes)" is returning a string without the trailing quotation. During a step-into, ClientData was "something instead of "something". If I manually put the other quotation on the end during a step-into, it would work. Why is this happening?

I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
View 15 RepliesI define some global variables of a class as follows:
Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)
Does the memory used in declaring variables are reclaimed by the OS when these variables go out of scope?Does the memory used be released by setting thier value to nothing? if not, then how can I force the garbage collector to run or excecute at a certain/desired time..How about in Windows Forms..How can we make sure that the memory used in initializing and showing forms be released if those forms were closed?

Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

View 5 RepliesI have a class that does four things: unzips and zips files, downloads and uploads files. It needs to complete all four actions for 9 different command line apps. Which means, unfortunately, that there needs to be 4 different strings for each time. All in all, I need to create 36 strings which are different command line arguments. I need to figure out the best way to accomplish this. Should I just create all 36 strings in the class? Or should I use a constructor? Or... properties? Maybe a structure?

Thats the thing with vb i dont understand is when you make a public variable, and when you change the value of the var in a sub, it doesnt change globally.

View 6 RepliesI'm trying to get a handle on creating my own Interfaces for a project I'm working on. I know the MSDN help shows that all member signatures will become Public when implmented, etc, etc. However, if I implement the IDisposable interface provided by the framework, comments and private members and fields show up! Not only that, but some of the methods have comments and code within!
How did they do that? And can comments, private fields and members, and predetermined code be declared as part of an interface by the average developer?
